DENTAL INSTRUMENT.

$PEGIFICATION forming part of Letters Patent No. 698,997, dated April29, 1902. Application filed February 8, 1901. Renewed December 17, 1901.Serial No. 86,281. (No model.)

To all whom it may concern:

Be it known that LJEssn W. MCCONNELL, a" citizen of the United States,residing at Cornelia, in the county of Habersham andState of Georgia,have invented certain new and specification.

This invention relates to new and useful improvements in dentalinstruments, and especially to an amalgam-carrier designed especiallyfor use in carrying amalgam from a bracket or table to the tooth of apatient, and in carrying out my invention I take a steel tool and solderor otherwise secure thereto a piece of silver or other suitable metal,which is afterward immersed in quicksilver for a number of hours, thusforming an alloy. The tip of the instrument after being removed is fileddown, forming a beveled surface, against which the pieces of amalgam forthe filling will adhere when brought into contact with each other.

Theinvention will be hereinafter more fully described and thenspecifically defined in the appended claims and is illustrated in theaccompanying drawings, in which 1 Figure l is a perspective view of aninstrument,showing the head secured thereto,which head is made of silverand beveled. Fig. 2 is a longitudinal sectional view through theinstrument.

Reference now being had to the details of the drawings by letter, Adesignates the shank having, an affinity for quicksilver. -of theinstrument thus formed of the piece portion of a dental instrument,which may be of any suitable shape or size, to one end of whichinstrument is soldered or otherwise secured a piece of. silver or othermetal The tip of silver secured to the steel instrument is immersed inquicksilver for a number of hours, which causes an alloy to be formed bythe action of the silver on the quicksilver.

After the instrument has been removed from the quicksilver the alloyedtip is preferably filed down, forming a smooth beveled surface B, whichsurface will be in a horizontal position when the instrument is held ina natural or normal position. By bringing the fiat beveled surface incontact with the small balls of the amalgam filling the balls, beingalso of a similar alloy, will adhere to the alloyed end of theinstrument and may be conveyed from the bracket or table to the mouth ofthe patient, where it may be easily deposited in the cavity of thetooth. I

, Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. An amalgam-carrier consisting of a dental instrument having a pieceof silver secured thereto, and a silver-amalgam coating on said Intestimony whereof I hereunto affix my I signature in presence of twowitnesses.
